Nvr2loud, you may have the answer. I looked up the harness I bought from etrailer.com. It looks like I ordered the wrong one. The one I ordered is for "older" GMC vehicles. The one for my 'burb is a different model #. I wrote etrailer.com to confirm this. I'll see what they say. If another $15 fixes my mistake, I will be pleased!
I drove 80 miles on Sunday without the brakes working, they worked when I left the campground, but stopped working by about the third stop. I thought it felt harder to stop the truck, but didn't pay much attention. When I came to a sudden stop for a turning vehicle, I realized that the truck was doing all the work. I stopped and did a re-level on my controller... and all was well. I've never had to re-level the controller before, I wonder if over time the vibration of driving has moved the level switch ever so slightly each trip. :)
